Features
Read full description

The BangShift Billy app works in conjunction with our Bluetooth controller and hydraulic manifold/valve assembly to allow a diaphragm clutch to be precisely engaged and slipped like an adjustable slipper clutch at the drag strip. With the app you can adjust the “bite” point of the clutch down to the millisecond and adjust the slip time from zero to 2.00 seconds. It will reduce damage to driveline components and reduce ET by allowing controlled, repeatable launches.
